Lattice QCD at finite density [PDF]
Proceedings of XXIVth International Symposium on Lattice Field Theory — PoS(LAT2006), 2006 I discuss different approaches to finite density lattice QCD. In particular, I focus on the structure of the phase diagram and discuss attempts to determine the location of the critical end-point. Recent results on the transiton line as function of the chemical potential ($T_c( _q)$) are reviewed.

Lattice QCD Applications on QPACE
Procedia Computer Science, 2011 QPACE is a novel massively parallel architecture optimized for lattice QCD simulations. A single QPACE node is based on the IBM PowerXCell 8i processor. The nodes are interconnected by a custom 3-dimensional torus network implemented on an FPGA. The compute power of the processor is provided by 8 Synergistic Processing Units.

Instanton dynamics in finite temperature QCD via holography
Nuclear Physics B, 2015 We investigate instantons in finite temperature QCD via Witten's holographic QCD. To study the deconfinement phase, we use the setup proposed in [1]. We find that the sizes of the instantons are stabilized at certain values both in the confinement and ...

Search of QCD phase transition points in the canonical approach of the NJL model
Physics Letters B, 2019 We study the Lee-Yang zeros in the canonical approach to search phase transition points at finite temperature and density in the Nambu-Jona-Lasinio (NJL) model as an effective model of QCD.

Radiative transitions in charmonium from lattice QCD
Journal of High Energy PhysicsThe coupling of various charmonium mesons to a photon is studied using lattice QCD, giving access to radiative form factors and transitions, and probing the mesons’ structure.

Heavy-Meson Decay Constants: Isospin Breaking from QCD Sum Rules
EPJ Web of Conferences, 2017 Compared with lattice QCD, isospin breaking of heavy-meson decay constants from QCD sum rules agrees for D mesons but disagrees (by a factor of four) for B mesons.

Recent results on the meson and baryon spectrum from lattice QCD
EPJ Web of Conferences, 2017 Recent lattice results on the meson and baryon spectrum with a focus on the determination of hadronic resonance masses and widths using a combined basis of single-hadron and hadron-hadron interpolating fields are reviewed.
